M6 Gear Ratios and 1/4 Mile Times

[Tom 06 GTO]

I posted this in a couple other forums, but no one seems interested. Maybe one of my fellow GTO owners?

I found this old spreadsheet for the M6 Camaros, specifically it was set up for my 99 Camaro SS M6.

I modified it to match, best I know, to the 06 GTO M6. Maybe 05 and 04, too? Let me know if you see anything wrong. But, from my experience and a little experimenting, these numbers seem to be 'spot on'.

On the 1/4 mile, you should be going through the traps right at the meat of the power curve in 4th gear... the 1:1 gear (least resistance?) which should help w/ the time slip numbers

On my 99 SS M6, you had to shift 3rd to 4th about a second before the traps. It would red line right about 106 mph in 3rd. I tried just blowing through in 3rd and a few times hit the rev limiter. When I didn't, I didn't post great numbers anyway.

I think that kind of set up (on the M6 f-bodies) made getting the best times more difficult.

I haven't run the GTO yet. But, it seems the 3.46 rear and slightly smaller tire diameter makes it a better setup for the 1/4 mile.

Any thoughts from the more 1/4 mile experienced guys?

on my GTO, I was in 4th by then anyway, trapping 111. shifting into 4th at like 99
